Numerical simulation of the RF plasma discharge in the Linac4 H$^−$ ion source / Mattei, S (CERN ; CRPP, Lausanne) ; Nishida, K (Keio U.) ; Onai, M (Keio U.) ; Lettry, J (CERN) ; Tran, M Q (CRPP, Lausanne) ; Hatayama, A (Keio U.)
This paper presents a Particle-In-Cell Monte Carlo Collision simulation of the Radio-Frequency (RF) plasma heating in the Linac4 H$^−$ ion source at CERN. The model self-consistently takes into account the electromagnetic field generated by the RF coil, the external static magnetic fields and the resulting plasma response, including a kinetic description of the charged species (e$^−$, H$^+$, H$^+_2$, H$^+_3$, H$^−$), as well as the atomic and molecular (vibrationally resolved) populations.

Influence of the cusp field on the plasma parameters of the Linac4 H− ion source / Briefi, S (U. Augsburg (main)) ; Mattei, S (CERN) ; Lettry, J (CERN) ; Fantz, U (U. Augsburg (main) ; Garching, Max Planck Inst. Plasmaphys.)
When the H$^−$ ion source of CERN’s Linac4 is operated in volume mode, a maximum of the extracted current is obtained at varying RF power. The power required for this maximum and its absolute value is strongly influenced by the cusp magnets installed at the source for electron confinement: without magnets, 15−20 mA are typically obtained at 20 kW whereas with magnets a factor of two more power is needed and 25−30 mA are achieved.

First experience with carbon stripping foils for the 160 MeV H− injection into the CERN PSB / Weterings, Wim (CERN) ; Bracco, Chiara (CERN) ; Jorat, Louise (CERN) ; Noulibos, Remy (CERN) ; van Trappen, Pieter (CERN)
160 MeV H− beam will be delivered from the new CERN linear accelerator (Linac4) to the Proton Synchrotron Booster (PSB), using a H− charge-exchange injection system. A 200 µg/cm2 carbon stripping foil will convert H− into protons by stripping off the electrons. [...]

The n_TOF facility: Neutron beams for challenging future measurements at CERN / Chiaveri, E (CERN ; U. Manchester (main) ; Seville U.) ; Aberle, O (CERN) ; Andrzejewski, J ; Audouin, L ; Bacak, M (CERN ; TU Vienna ; IRFU, Saclay) ; Balibrea, J ; Barbagallo, M ; Bečvář, F ; Berthoumieux, E ; Billowes, J et al.
The CERN n_TOF neutron beam facility is characterized by a very high instantaneous neutron flux, excellent TOF resolution at the 185 m long flight path (EAR-1), low intrinsic background and coverage of a wide range of neutron energies, from thermal to a few GeV. These characteristics provide a unique possibility to perform high-accuracy measurements of neutron-induced reaction cross-sections and angular distributions of interest for fundamental and applied Nuclear Physics.

The Design, Construction and Operation of the Beam Instrumentation for the High Intensity and Energy Upgrade of ISOLDE at CERN / Andreazza, William (CERN) ; Bravin, Enrico (CERN) ; Cantero, Esteban (CERN) ; Carmona, José Miguel (AVS, Elgoibar) ; Galipienzo, Julio (AVS, Elgoibar) ; Noguera Crespo, Pedro (AVS, Elgoibar) ; Sadovich, Sergey (CERN) ; Sosa, Alejandro (CERN) ; Veness, Raymond (CERN)
The High Intensity and Energy (HIE) upgrade to the on-line isotope separation facility (ISOLDE) facility at CERN is currently in the process of being commissioned. The very tight space available between the superconducting acceleration cavities used and a challenging specification led to the design of a compact 'diagnostic box' with a number of insertable instruments on a common vacuum chamber.
